One of the advantages of entering the structure in RFEM is the complete freedom when selecting the geometry. Therefore, it is easily possible to select a structure where re‑entrant rolling corners are given as shown in the picture.

One of the advantages of entering the structure in RFEM is the complete freedom when selecting the geometry. You can easily select a structure where re‑entrant rolling corners are given as shown in the image.
The support of the cross-laminated timber panel deserves special attention. Usually, a cross‑laminated wall is secured against shearing by means of shear connectors and against lifting forces by means of tie rods.
To better distinguish between the different layer compositions (for example, for walls and ceilings), you can assign user‑defined colors and textures to each composition.
In this article, we will look at the design of shear connectors of cross‑laminated timber structures that transfer the longitudinal forces of the shear wall to the soil.
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
- Binderholz (USA)
- KLH (USA, CAN)
- Kalesnikoff (USA, CAN)
- Nordic Structures (USA, CAN)
- Mercer Mass Timber
- SmartLam
- Sterling Structural
- Superstructures listed in Lignatec Edition 32 "Cross-Laminated Timber of Swiss Production"
By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.
The Timber Design add-on for RFEM 6 / RSTAB 9 is multi-purpose and combines a large number of additional elements. [*S16332764*] Timber Design Add-on for RFEM 6
How does the "Orthotropic Plastic" material model work in RFEM?
How is it possible to display the RF‑LAMINATE library? We would like to check that it is up to date.
Can I use surface releases to separate two overlapping surfaces?
How can I model a timber beam with stiffening on both sides? (splice)
How can I generate an area load on members via cells in RFEM 6 or RSTAB 9?
Which programs do I need for laminate and sandwich structures, or cross-laminated timber (CLT)?
